This is an highlight of the HSI features. Please, visit the HSI Home Page for more information.

HSI is a friendly interface for users of the High Performance Storage System (HPSS). It is intended to provide a familiar Unix-style environment for working within the HPSS environment, while automatically taking advantage of the power of HPSS (e.g. for high speed parallel file transfers) without requiring any special user interaction, where possible.

HSI requires one of two authentication methods (see the HSI User Guide for more information):

• Kerberos (the preferred method)
• DCE keytab (using a keytab file generated for you by the HPSS system administrators)

HSI's features include:

• Familiar Unix-style command interface, with commands such as "LS", "CD", etc.
• Interactive, batch, or "one-liner" execution modes
• Ability to interactively pipe data into or out of HPSS, using filters such as "TAR"
• Recursive option is available for most commands; including the ability to copy an entire directory tree to or from HPSS with a single simple command
• Conditional put and get operations, including ability to update based on file timestamps
• Automatically uses HPSS parallel I/O features for file transfer operations
• Multi-threaded I/O within a single process space
• Command aliases and abbreviations
• 10 working directories
• Ability to read command input from a file, and write log or command output to a file.
• Non-DCE version runs on most major Unix-based platforms
• Non-DCE version provides the ability to connect to multiple HPSS systems and perform 3rd-party copies between the systems, using a "virtual drive" path notation.
